v2.3.1

Added

• Added "Genre" field to universes.
• Added language link to locations, and "Locations spoken" context card to language pages.

Changed

• Content context cards now "group up" per content type into a single card when they would have multiple context cards with one item in each list.
• Context cards can now use custom titles, with support for a <plural> token that replaces e.g. "4 locations" anywhere in the string.

Fixed

• Content linking no longer excludes same-id, different-class options (e.g. Location 1 not showing Character 1 in dropdowns), #193.
